山西省小杂粮生产病害防治现状评价

采用文献资料法和现场调查相结合的方法,研究了山西省小杂粮谷子、糜子、荞麦、莜麦、绿豆传统生产过程中的病害防治现状.结果表明,5种小杂粮的常见病害共23种,其中6种病害的化学防治中使用了绿色食品禁用药品,且大多数病害防治以化学防治为主.提出加强农业防治,优先物理防治,提倡生物防治,巧用化学防治,使其生产过程真正符合绿色食品生产的要求.并建议根据绿色食品病害防治要求,更新相关教材、专著病害防治内容.     

Flexure-torsion Analysis of Variable-curvature-box Girder Considering Non-coincidence of Torsion Center and Gravity Center

In order to consider the effect of non-coincidence of torsion center and gravity center,the rectangular variable-curvature-box girder with vertical symmetrical axis is studied. Considering the influence of shear deflection and non-coincidence of torsion center and gravity center, the elastic equilibrium formulas are established. Based on deformation equations of the girder and the relations of inner forces and deformations,the flexure-torsion differential equations are developed. The equilibrium differential equations and Galerkin methods formulas for clothoid curved box girder are presented.     

Investigation and Reference of the Mountain Tourist Hotel in Western Sichuan

Tourist hotel is the main supporting establishment for the touring industry.The authors investigated several important mountain beauty spots in the west of Sichuan province,some problems were found and their reasons were studied.Then,some common characters of mountain tourist hotels were summarized.It is hoped to give some reference to congenial buildings in west China in the future.     

A.A. Marcov Forecast Method of the System Ration in Estate Business Study

A. A. Markov Rolling Forecast Method is presented in this paper according to the dynamic characteristics of the estate business system. Test results reveal that the system quantitative forecast could be realized on the basis of previous samples, which provide a direction of the rational management in estate business. Concerning sample molding analysis and Markov Rolling Forecast Method, this paper gives a corresponding conclusion of analytic research quantitatively in order to demonstrate the formation of factors working in estate business activities and its systematic logistic connotation. Markov Rolling Forecast Method can be applied not only to short-term prediction but long term one as well, provided when the market is rather stable with no significant change during a regular period of time and when the rolling times of the state transition matrix are fairly enough.     

The Buyer Cancellation Claim and the Tenant Priority Claim in Auction--Analyzing the Disputes in An Auction Case

Two problems often appear in estate auction.The first is to whom the buyer can claim cancellation of the contract,if he can't get the estate.The second is whether the tenant can still claim his priority to the estate.In auction,we can't use the principle of agency,fiduciary and mediation to explain the relations among client,auctioneer and buyer,because it doesn't accord with the auction practices and the Action Law section 40.The undisclosed agency in Contract Law may be an adapt explanation to the relations.According to the law hermeneutic,we should narrow the scopes of the tenant priority and exclude it from auction.     

Accomplishment of Elastic-plastic Analysis in Geotechnical FEA

In order to realize elastic-plastic analysis in geotechnical FEA, in this paper, firstly, the method how to realize elastic-plastic analysis in Super-Sap is discussed. Then, this paper stresses to introduce the principle and the steps used to achieve the accomplishment of elastic-plastic analysis in Super-Sap. Finally, an engineering practice is given to prove that the geotechnical FEA elastic-plastic analysis and visualized post-processing can come true by it rapidly.
